"They're underground?" Feng Ruxue was shocked to hear that.
"Yes." Ling Yun then pointed towards the distance. "Currently, they are in that area, but I still didn't expect that they could develop such advanced technologies."
Feng Ruxue observed that distant area as she asked Ling Yun again. "Is their technology really that advanced?"
"If we compare with the outside world, their technology is more advanced." Ling Yun replied as he nodded. "However, their technology is still incomparable to Xiao Yin and everything else within the Fortress."
"After all, Tang Xiao is the ruler of his universe, and he also obtained a lot of technology from the future." Feng Ruxue answered as she shook her head.
"That's true." Ling Yun then raised his eyebrows when he saw Lucas landing not far from that area, and he used his lightning to check underground. "Honestly, I never thought that Lightning could be used for such a thing, especially since its destruction power is quite strong."
